This workshop introduces a freely-available system in which students may make weather forecasts using the Internet. The forecasts involve predictions of selected weather elements (daily high and low temperatures, wind, etc.), as well as justifications for these predictions. Forecasts are automatically emailed to the teacher, where they can be assessed according to the needs of the curriculum.
The forecasting system has been shown to improve critical thinking skills, as well as to enhance student enthusiasm through investigating problems for which "even the teacher doesn't know the answer".
